Effects of Charge

Summary of Key Points

Particles are attracted to substrates (or other particles) via certain types of interactions. These interactions create stresses between the materials. These stresses, in turn, create strains that may be large or small, elastic or plastic.
  • Only by understanding both the interactions and the mechanical response of the materials to these interactions can adhesion be understood.

The JKR model is the underlying theory on which most of our present understanding of adhesion is based.

This presentation will focus on particle adhesion.However, just as the JKR theory describes adhesion between macroscopic bodies, the concepts presented can be readily generalized to other situations.
